Abstract

An inexpensive screen for projector that can be installed/uninstalled easily and providing a favorable image visibility both at indoor and outdoor places even if the image is projected from an indoor room (that is, even if an image is projected onto either side, the image can be viewed favorably from both sides). Yupo paper (that is produced and sold by YUPO Corporation and is a semitransparent synthetic paper mainly made of a polypropylene resin. A trade name) (10) is used as the screen for projector. Since the Yupo paper (10) is semitransparent, even if an image is projected from one side, the light is not transmitted through the screen, and most part of the light is used to form the image on the screen. The projected image can be viewed not only from the projection side but also from the opposite side clearly. Even if the angle of projection by projector onto the screen (the angle between the optical axis of the light from the projector and the screen) is considerably small, the projected image on the screen is sufficiently clear.

Description

明 細 書 両面視認型プロジェクタ投映用スクリーン 技術分野  Description Double-sided projection projector screen Technical field
本発明は、 ショーウインドーやビルなどのディスプレイやスタンド型 '吊り下 げ型等として用いるプロジェクタ投映用スクリーンに関する。 背景技術  The present invention relates to a projector projection screen used as a display such as a show window or a building, or as a stand type or a hanging type. Background art
店頭や街頭において、 一定時間毎に変化する静止画や動画を表示することによ り効果的な宣伝 ·広告を行うことが近年広く行われるようになつてきた。 実用化 されているものでは、 ビルなどの壁面に大形のブラウン管ゃ液晶或 ^はプラズマ 等の表示装置を設置して映像を表示する方法や、 壁面にスクリーンを張設してそ こに映像を投映する、 或いは白色とした壁面自体に映像を投映するという方法が ある。 このうち、 壁面にブラウン管、 液晶、 プラズマ等の表示装置を設置する方 法では、 いずれの表示装置を用いるにせよコストが非常に高く、 また、 その設置 は半永久的なものとなってしまう。 一方、 壁面にスクリーンを張設したり、 壁面 自体をスクリーンとする方法では、 コストは遙かに低く、 設置 ·取り外しも容易 であるが、 外部に投映装置を設けなければならず、 精密光学機械である投映装置 の雨露や塵埃からの保護という問題がある。  In recent years, effective advertising has been widely practiced in stores and streets by displaying still images and moving images that change at regular intervals. In practical use, a large cathode ray tube (LCD) or a display device such as plasma is installed on the wall of a building or the like to display an image, or a screen is stretched on the wall and an image is displayed there. There is a method of projecting an image or projecting an image on the white wall itself. Among them, the method of installing a display device such as a cathode ray tube, a liquid crystal, a plasma, etc. on the wall surface is extremely expensive regardless of which display device is used, and the installation is semi-permanent. On the other hand, the method of installing a screen on the wall surface or using the screen itself as the screen itself is much lower in cost and easy to install and remove, but it requires an external projection device and requires precision optics. There is a problem that the projection device is protected from rain, dew, and dust.
そこで、 ショーウインドーのガラス面にスクリーンを設け、 屋内側からプロジ ェクタでそのスクリーン上に映像を投映するという方法が盛んに行われている。 この方法には、 投映装置の保護に関する問題が少ない、 映像品質の劣化が少ない 、 高さをほぼ歩行者等の目の高さと同じにすることができるため視認者側からの 視認性が優れている、 等の多くの利点がある。  Therefore, a method is widely used in which a screen is provided on the glass surface of the show window and images are projected on the screen by a projector from the indoor side. In this method, there are few problems concerning the protection of the projection device, there is little deterioration of the image quality, and the height can be almost the same as the height of eyes of a pedestrian or the like, so that the visibility from the viewer side is excellent. There are many advantages, such as:
屋内投映方法において、 ショーウインドーのガラス面に設けるスクリーンにも 各種方法があるが、 一つには、 ガラス面に白色の粉末を吹き付け固定し或いは塗 料を薄く塗布し、 スクリーン面とする方法がある。  In the indoor projection method, there are various methods for the screen provided on the glass surface of the show window.One method is to fix the glass surface by spraying white powder or apply a thin coat of paint to make the screen surface .
差換え用紙（規則 26) ガラス面に粉末を吹き付けたり塗料を塗布する方法では、 そのショーウィンド 一においてスクリーンが固定されてしまい、 後に透明のガラス面に戻すことが不 可能であったり面倒な作業が必要となる。 Replacement paper (Rule 26) In the method of spraying powder or applying paint to the glass surface, the screen is fixed in the show window, and it is impossible to return to the transparent glass surface later, and laborious work is required.
このため、 ガラス面の内側に半透明のスクリーンを吊り下げ或いは貼付する方 法が考えられる。 し力 ^し、 屋内側から投映し、 それを屋外側から良好に視認させ るためには、 スクリーンは適度な半透明性を有さなければならない。 スクリーン 力 S透明すぎると、 投映光の多くがスクリーンを透過してしまい、 スクリーンに投 映される映像が弱くなつてしまうとともに、 投映光以外の屋内側からの光が視認 者側に向かうため、 映像は極めて不鮮明なものとなる。 一方、 スクリーンの透明 度を低くし過ぎると、 屋内側 （投映側） からの映像の視認性は良好であるが、 肝 心の屋外側からは映像が殆ど視認できないということになる。  For this reason, it is conceivable to suspend or attach a translucent screen inside the glass surface. The screen must have an appropriate degree of translucency so that it can be projected from the indoor side and viewed well from the outdoor side. If the screen power is too transparent, much of the projected light will pass through the screen, weakening the image projected on the screen, and light from the indoor side other than the projected light will be directed to the viewer. The image will be very unclear. On the other hand, if the transparency of the screen is too low, the visibility of the image from the indoor side (projection side) will be good, but the image will be almost invisible from the outdoor side.
本発明はこのような課題を解決するために成されたものであり、 その目的とす るところは、 設置及び取り外しが容易であり、 且つ、 屋内からの投映であっても 、 屋内 '屋外共に良好な映像視認性を提供することができる （すなわち、 いずれ の面から投映しても、 両面において良好な映像視認性を提供する） 安価なプロジ ェクタ投映用スクリーンを提供することにある。 発明の開示  The present invention has been made in order to solve such a problem, and an object of the present invention is to easily install and remove, and even when projecting from indoors, both indoors and outdoors. It is an object of the present invention to provide an inexpensive projector projection screen that can provide good image visibility (that is, it provides good image visibility on both sides, regardless of the projection direction). Disclosure of the invention
上記課題を解決するために成された本発明に係る両面視認型プロジェクタ投映 用スクリーンの第 1の態様のものは、 スクリーン部をュポ紙のみで構成レたこと を特徴とする。  A first aspect of a double-sided projection projector projection screen according to the present invention, which has been made to solve the above-mentioned problem, is characterized in that the screen portion is composed of only lipo paper.
また、 本発明に係る両面視認型プロジェクタ投映用スクリーンの第 2の態様の ものは、 ュポ紙を 2枚の透明板で挟んで構成したことを特徴とする。 ュポ紙とは、 株式会社ュポ .コーポレーションが製造 ·販売する、 ポリプロピ レン樹脂を主原料とする半透明の合成紙で、 トレースや商業印刷、 パッケージ、 情報用紙として用いられている。 なお、 「ュポ」 は登録商標 （登録第 2721062号 ) である。  A second aspect of the double-sided projection projector screen according to the present invention is characterized in that the paper is sandwiched between two transparent plates. Upo Paper is a translucent synthetic paper made and sold by Upo Corporation and made of polypropylene resin, and is used as trace, commercial printing, packaging, and information paper. “UPO” is a registered trademark (Registered No. 2721062).
本願発明は、 このュポ紙をプロジェクタ投映用のスクリーンとして用いるもの  The invention of the present application uses this upo paper as a screen for projector projection.
2 Two
差換え用紙（規則 26) である。 上記の通り、 ュポ紙は半透明であるため、 一方から映像を投映してもそ の光がスクリ一ンを透過することなく、 殆どの光がスクリーン上の映像形成に使 用される。 なお且つ、 その投映映像は、 投映面側からだけではなく、 反対側の面 からも明瞭に視認することができる。 しかも、 プロジェクタからスクリーンへの 投映角度 （プロジェクタからの光の光軸とスクリーン面との間の角度） が相当小 さくても、 スクリーン上での投映映像は十分鮮明である。 Replacement paper (Rule 26) It is. As mentioned above, because the translucent paper is translucent, even if an image is projected from one side, the light does not pass through the screen, and most of the light is used to form an image on the screen. In addition, the projected image can be clearly seen not only from the projection side but also from the opposite side. Moreover, even when the projection angle from the projector to the screen (the angle between the optical axis of the light from the projector and the screen surface) is considerably small, the projected image on the screen is sufficiently clear.
なお、 特開 2001-22000号公報には、 ュポトレーシングフィルムを用いたリアス クリーン用口一ル式ブラインドが開示されている （[0028]及び図 5 ) が、 これは 元来ブラインドであるため、 透明な基材 （ 「ポリカーボネ一卜フィルム材質の透 明アクリル樹脂」 ） を必須としている。 それに対し、 本発明ではュポ紙のみでス クリーンを構成するため、 ガラス面への貼付も容易であり、 後述の巻上式スクリ ーンとする場合も、 取り扱いが容易である。 また、 透明基材側の面ではその面か らの反射光が投映光と共に視認者の目に入るため、 投映映像の視認性が劣るとい う問題点もある。 それに対し、 本発明では両面とも反射光がほとんど生じず ス クリーン面に投映された映像のみが視認者の目に入り、 良好に視認される。  In addition, Japanese Patent Application Laid-Open No. 2001-22000 discloses a mouth-type blind for rear screen using a hyper-tracing film ([0028] and FIG. 5). However, this is originally a blind. A transparent substrate (“transparent acrylic resin made of polycarbonate film”) is essential. On the other hand, in the present invention, since the screen is composed only of the upo paper, the screen can be easily attached to the glass surface, and the winding screen described later can be easily handled. Also, on the surface on the transparent substrate side, the reflected light from the surface enters the eyes of the viewer together with the projected light, and thus there is a problem that the visibility of the projected image is poor. On the other hand, in the present invention, almost no reflected light is generated on both surfaces, and only the image projected on the screen surface enters the eyes of the viewer, and is viewed well.
ュポ紙には種々の厚さのものが用意されているが、 両面からの視認性を良好に するためには、 50〜90 ΠΙ程度の厚さのものを使用するのが好ましい。 両面を透明 板で挟む場合やスクリーン面の面積が小さい場合、 或いはガラス面等に貼付する 場合には、 このうち比較的薄手のもの （50〜70 m程度） が適しており、 後述の巻 上式のように強度も必要とされる場合には、 比較的厚手のもの （60〜90 x m程度） を使用することが望ましい。 図面の簡単な説明  Although various thicknesses of the paper are available, it is preferable to use a paper having a thickness of about 50 to 90 mm in order to improve the visibility from both sides. When the both sides are sandwiched between transparent plates, when the area of the screen surface is small, or when affixed to a glass surface, etc., a relatively thin one (about 50 to 70 m) is suitable. When strength is also required as in the formula, it is desirable to use a relatively thick one (about 60 to 90 xm). BRIEF DESCRIPTION OF THE FIGURES

BEST MODE FOR CARRYING OUT THE INVENTION
本発明に係るスクリーンは、 種々の態様で使用することができる。 まず、 第 1 図に示すように、 透明ガラス面 1 1に貼付する方法がある。 ュポ紙 1 0は比較的 軽量であるため、 そう大きなスクリーンとするのでなければ、 貼付の際に接着剤 を全面に付着させる必要はなく、 周囲のみ、 或いは上辺のみをガラス面 1 1又は その周囲の枠 1 2に接着するだけで十分全体を保持することが可能である。 適切 な接着剤を選定することにより、 不要となった際のスクリーン 1 0の取り外しも 極めて容易であり、 跡も残らない。 ュポ紙は比較的安価であるため、 スクリーン 1 0が汚れたときは容易に交換することができる。  The screen according to the present invention can be used in various modes. First, as shown in FIG. 1, there is a method of sticking to a transparent glass surface 11. Since the paper is relatively lightweight, it is not necessary to apply an adhesive to the entire surface when applying it unless a large screen is used. It is possible to sufficiently hold the whole by simply adhering to the surrounding frame 12. By selecting an appropriate adhesive, it is extremely easy to remove the screen 10 when it is no longer needed, leaving no trace. Since the paper is relatively inexpensive, it can be easily replaced when the screen 10 becomes dirty.
また、 第 2図に示すように、 従来より広く使用されている巻上式 （ロールアツ プ式） スクリーン 2 0とすることもできる。 この方式のスクリーン 2 0を使用す る場合、 必ずしもショーウインドー等のガラス面の内側で用いる必要はなく、 部 屋の中央に設けることもできる。 これにより、 両側から映像を楽しむことのでき るパーティションとしても使用することができる。 ュポ紙は強度が高いため、 高 さ 2m程度の大きさのスクリーンを構成し、 第 2図に示すように下辺に安定用重錘 棒 2 3を装着しても破れることなく、 安定して使用することができる。 なお、 不 要の場合には、 巻上紐 2 4で巻き上げることにより、 スクリーン 2 0は上部のケ ース 2 1内に収納される。 また、 半分だけ巻き上げて天井近くの部分にだけスク リーンを設け、 下は通り抜け可能として頭上にのみ投映するという使い方も可能 である。 このような使い方をするときは、 プロジェクタ 2 2は上部に設ける （天 井吊り下げ型とする） ことが望ましい。  Further, as shown in FIG. 2, a roll-up (roll-up) screen 20 which has been widely used conventionally can be used. When using the screen 20 of this type, it is not always necessary to use it inside the glass surface of a show window or the like, and it can be provided in the center of a room. As a result, it can be used as a partition from which video can be enjoyed from both sides. Because the paper has a high strength, a screen with a size of about 2 m in height is constructed, and even if the stabilizing weight bar 23 is attached to the lower side as shown in Fig. 2, it will not break and will stably Can be used. When unnecessary, the screen 20 is stored in the upper case 21 by winding it up with the hoisting cord 24. It is also possible to wind up only half of the screen and provide a screen only near the ceiling, and project underneath as it can pass underneath. In such a case, it is desirable that the projector 22 be provided at the top (to be suspended from the ceiling).
更には、 第 3図に示すように、 ュポ紙 3 1を 2枚の透明板 3 2、 3 3で挟んで もよい。 両面を透明板 3 2、 3 3で挟む場合、 透明板 3 2、 3 3としてはァクリ ル板を使用することが望ましい。 アクリル板は高い透明度を有するため視認度を 良好に保持することができる上、 強度も兼ね備えているため、 薄い板で大きなス クリーンを構成することが可能となる。 2枚の透明板で挟んだスクリーンは、 床  Further, as shown in FIG. 3, the paper 31 may be sandwiched between two transparent plates 32, 33. When the transparent plates 32 and 33 are sandwiched on both sides, it is preferable to use acrylic plates as the transparent plates 32 and 33. Acrylic plates have high transparency and can maintain good visibility, and also have strength, so that a large screen can be constructed with a thin plate. The screen sandwiched between two transparent plates
4 Four
差換え用紙（規則 26) に立てるスタンド型としてもよいし、 天井からの吊り下げ型としてもよい。 第 4 図に、 スタンド型の両面視認型プロジェクタ投映用スクリーンの一例を示す。 こ のスクリーン 4 0では、 ュポ紙 4 1 (620mmX 1100mm) を 2枚のアクリル板 4 2 ( 730腿 X l OimnX厚さ 5匪） で挟み、 下辺で固定して、 1本の伸縮可能な脚 4 3及 びフロアプレート 4 4で床上に置くようにしたものである。 Replacement paper (Rule 26) It may be a stand type that stands upright or a type that hangs from the ceiling. Fig. 4 shows an example of a stand-type double-sided view projector projection screen. In this screen 40, the paper 4 1 (620mm x 1100mm) is sandwiched between two acrylic plates 4 2 (730 thigh X l OimnX thickness 5 bandages), fixed at the lower side, and one stretchable The feet are placed on the floor with legs 4 3 and floor plates 4 4.
これら以外にも、 本発明の第 2の態様に係るスクリーンは、 普段は壁面や天井 に平行に収納しておき、 必要なときに壁面や天井に垂直に （又は角度を持たせて ) 立て、 スクリーンとして使用するような形態でも使用することができる。  In addition to the above, the screen according to the second aspect of the present invention is usually stored parallel to a wall or ceiling, and stands upright (or at an angle) on the wall or ceiling when necessary. A form used as a screen can also be used.
